“…Polyacrylic acid was an effective dispersing agent for large-sized MWCNTs in acidic copper sulfate baths [35,[62][63][64][65][66][67][68][69][70][71][72]. Cu/MWCNT composite powder [35] and films [62] were fabricated by electrodeposition using a sulfate bath containing a polyacrylic acid as the dispersing agent.…”

Metal/carbon nanotube (CNT) composites are promising functional materials due to the various superior properties of CNTs in addition to the characteristics of metals, and consequently, many fabrication processes of these composites have been vigorously researched. In this paper, the fabrication process of metal/CNT composites by electrochemical deposition, including electrodeposition and electroless deposition, are comprehensively reviewed. A general introduction for fabrication of metal/CNT composites using the electrochemical deposition is carried out. The fabrication methods can be classified into three types: (1) composite plating by electrodeposition or electroless deposition, (2) metal coating on CNT by electroless deposition, and (3) electrodeposition using CNT templates, such as CNT sheets and CNT yarns. The performances of each type have been compared and explained especially from the view point of preparation methods. In the cases of (1) composite plating and (2) metal coating on CNTs, homogeneous dispersion of CNTs in electrochemical deposition baths is essential for the formation of metal/CNT composites with homogeneous distribution of CNTs, which leads to high performance composites. In the case of (3) electrodeposition using CNT templates, the electrodeposition of metals not only on the surfaces but also interior of the CNT templates is the key process to fabricate high performance metal/CNT composites.

“…There are several ceramic reinforcements, such as SiC [20], TiC [21], Al2O3 [22], ZrO2 [23], GO [24], La2O3 [25], ZrB2 [26], CNTs [27], CNTs-Gr hybrid [28], TiC-SiC hybrid [29], have been used to boost the mechanical properties of Cu, usually at the expense of electrical and thermal conductivity. The incorporation of chemically stable hard ceramic particles is an alternative and feasible method for improving the mechanical and wear action of Cu.…”

Cu-(TiC/Al2O3) nanocomposite was synthesized successfully using the powder metallurgy route. The constituents are first ball-milled and then sintered using the spark plasma sintering technique. The tribological and physical properties are investigated. The homogeneity and of ceramics distribution were also evaluated using SEM and XRD. Results showed that TiC and Al2O3 nanoparticles were homogeneously distributed all over the Cu matrix. Copper reinforced with 3 wt.% Al2O3 and hybrid (3 wt.% TiC and Al2O3) had the lowest relative density (95%). The hybrid (3wt. % TiC and Al2O3) sample had a higher wear rate value (1.7*10 -3 ) at 25 N load, while the sample reinforced with 3 wt.% TiC had the lowest value (0.5*10 -3 ) at 25 N load. Cu-Al2O3 exhibited a higher hardness value (149 HV). The highest electrical and thermal conductivities are recorded for the Cu-TiC that were (20.76 MS/m) and (149.03 W/m. k) respectively

“…Compared with traditional electrodeposition, jet-electrodeposition accelerates the transport of electrodeposition materials and increases the limit current density, thereby accelerating the speed of ion deposition. Under the impact of the plating solution, the thickness of the surface diffusion layer is effectively reduced, and the excessive growth of the crystal grains in the vertical direction is suppressed; thus, a dense plating layer structure and refined crystal grains are obtained [9][10][11][12][13][14]. Compared with a pure Ni coating, a Ni−P alloy coating has excellent physical, chemical, and mechanical properties, and is an alternative to pure Ni coating as an ideal metal substrate protection layer.…”

To improve the wear resistance of 45 steel surfaces, a Ni−P alloy coating was prepared on the surface of 45 steel with an immersion-assisted jet-electrodeposition technology. Scanning electron microscopy, energy dispersive spectrometry, X-ray diffraction and confocal microscopy were used in testing the surface morphology, composition, structure, grain size, and wear scar parameters of the coating. The effect of immersion-assisted jet-electrodeposition on the wear resistance of Ni−P alloy coating at current densities of 20–60 A·cm−2 were explored and analyzed. Results showed that the surface quality, microhardness, and wear resistance of Ni−P alloy coatings prepared through immersion-assisted jet-electrodeposition were improved compared with those of the coatings prepared through traditional jet-electrodeposition. With the increase in the current density, the surface cell structure of the alloy coating was refined, the flatness was improved, the surface Ni content was increased, the grain size was refined, and the coating thickness, the microhardness, and wear resistance showed a trend of first increasing and then decreasing. The best surface quality of the coating was observed at a current density of 50 A·cm−2. Moreover, the unit cell structure was obvious, the surface was flat and dense, the coating thickness was the largest, reaching 21.42 μm, the highest Ni content was obtained (98.25 wt.%), the smallest grain size (6.6 nm) was obtained, the microhardness of the coating reached a maximum value (725.58 HV0.1), and the best wear resistance was observed.
